Jim Laskey 5ba7c23cdd Bug#834 ICE (crash in code generator?) when building PCH . 
Missing Darwin check in Intel ATT ASM printer.

 2006-07-19 11:54:50 +00:00
Jim Laskey a7b2bd5997 Add and sort "sections" in debug lines. This always stepping through 
code in sections other than ".text", including weak sections like ctors and
dtors.

Jim Laskey f67bec0579 Place dwarf headers at earliest possible point. Well behaved when skipping 
functions.

Chris Lattner d0201946ad Fix the MASM asmprinter's lies. It does not want to emit code to .text/.data 
it wants it emitted to _text/_data.

Evan Cheng 9733bde74c Fixing truncate. Previously we were emitting truncate from r16 to r8 as 
movw. That is we promote the destination operand to r16. So
        %CH = TRUNC_R16_R8 %BP
is emitted as
        movw %bp, %cx.

This is incorrect. If %cl is live, it would be clobbered.
Ideally we want to do the opposite, that is emitted it as
        movb ??, %ch
But this is not possible since %bp does not have a r8 sub-register.

We are now defining a new register class R16_ which is a subclass of R16
containing only those 16-bit registers that have r8 sub-registers (i.e.
AX - DX). We isel the truncate to two instructions, a MOV16to16_ to copy the
value to the R16_ class, followed by a TRUNC_R16_R8.

Due to bug 770, the register colaescer is not going to coalesce between R16 and
R16_. That will be fixed later so we can eliminate the MOV16to16_. Right now, it
can only be eliminated if we are lucky that source and destination registers are
the same.

Evan Cheng ddb6cc1d8e Better implementation of truncate. ISel matches it to a pseudo instruction 
that gets emitted as movl (for r32 to i16, i8) or a movw (for r16 to i8). And
if the destination gets allocated a subregister of the source operand, then
the instruction will not be emitted at all.

Nate Begeman b9d4f8324d Extend printBasicBlockLabel a bit so that it can be used to print all 
basic block labels, consolidating the code to do so in one place for each
target.

llvm-svn: 28014
 2006-04-28 21:19:05 +00:00
Nate Begeman 4ca2ea5b43 JumpTable support! What this represents is working asm and jit support for 
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.

Evan Cheng 7714a59d91 Missing .globl for weak / link-once .text symbols. 
llvm-svn: 26321
 2006-02-22 23:59:57 +00:00
Evan Cheng 73136dfecc - Added option -relocation-model to set relocation model. Valid values include static, pic, 
dynamic-no-pic, and default.
PPC and x86 default is dynamic-no-pic for Darwin, pic for others.
- Removed options -enable-pic and -ppc-static.

Nate Begeman 6f8c1ace6e No longer track value types for asm printer operands, and remove them as 
an argument to every operand printing function.  Requires some slight
tweaks to x86, the only user.

Chris Lattner 618981fd03 Naturally align doubles in the constant pool, set PrivateGlobalPrefix on 
darwin, use it when printing the constant pool indices so the labels are
appropriately private, emit cp entries to .const instead of .data on darwin
and only emit a single .section for the constant pool, not one for each
entry.
